In this position, as the bolt handle is lifted it will first withdraw the striker back into the bolt away from the head of the fired case, this being accomplished by cam action. As the bolt handle is lifted through 90 degrees to the left, and drawn straight back, it will withdraw the empty cartridge case and strike it against the ejector to hurl it out of the rifle.
As the bolt travels back and ejects, it will ride down the head of the pivoted cartridge elevator on which a cartridge is resting. This will lift the front end of the elevator, whose nose will block the cartridge in the magazine from moving forward under the influence of the magazine spring in the tube.
MODEL 71-84. RIGHT SIDE PHANTOM VIEW SHOWING ACTION OPEN AND IN FULL REAR POSITION, EMPTY CASE EJECTED, ELEVATOR RAISED READY TO FEED CARTRIDGE AND TUBE BLOCKED
The bolt head traveling to the rear and forcing down the rear head of the elevator has tilted it to bring the cartridge in the elevator trough up into line with the feeding face of the bolt.
When the bolt is thrust forward, the head of the bolt will start the cartridge forward into the chamber and continued further movement of the bolt will ride over the elevator trough and force it down. When the hooked front end of the trough has been lowered far enough, it will line up with the cartridge in the magazine tube. The compressed spring within the tube, forcing the follower will drive the cartridge into the elevator trough ready for the next lifting movement in feeding.
Closing the bolt will completely chamber the cartridge and spring the extractor around the head of the cartridge case.
Turning the bolt handle down will act through the standard Mauser cam action to force the cocking-piece back to full cock and enable the sear to engage and hold the striker back ready for firing.
